Answer:To find n(F), which represents the number of elements in set F, you simply count the distinct elements in the set.Given the set F=g,y,s,g,o,q,l,m,n, note that g appears twice, but we only count it once since sets do not have repeated elements.So, the distinct elements are: g,y,s,o,q,l,m,n.Therefore, n(F)=8.
